`tryWrite` method?

[aadityataparia]

Is there a tryWrite method like tryEnd or can there be?

difference with tryEnd being it won't require size argument when writing, but will give backpressure handling capability.

Example usage:

    readStream.on('data', (buffer) => {
      const chunk = buffer.buffer.slice(buffer.byteOffset, buffer.byteOffset + buffer.byteLength),
        lastOffset = res.getWriteOffset();

      // First try
      const ok = res.tryWrite(chunk);

      if (!ok) {
        // pause because backpressure
        readStream.pause();

        // Save unsent chunk for later
        res.ab = chunk;
        res.abOffset = lastOffset;

        // Register async handlers for drainage
        res.onWritable((offset) => {
          const ok = res.tryWrite(res.ab.slice(offset - res.abOffset));
          if (ok) {
            readStream.resume();
          }
          return ok;
       });
      }
    });
    readStream.on('end', () => res.end());

or are there are alternatives?

Try write is like try end but without a pre known size yes (content length vs chunked encoding)

Oh wait, there is no try write. You have to write smaller chunks like 16kb or 4kb.

But can there be one? it would be useful IMO.

Yes it can be added but I haven't thought about how. You can send smaller chunks for now
